GPIB-ENET/100 Hardware Overview
The GPIB-ENET/100 high-speed interface controls GPIB instruments
acrossE thernetnetw orks.You can use theGPIB -ENET/100to access
remotetest equipment from anywhere in the world via TCP/IP protocols on
10Base-Tand 100Base-TX networks. By incorporating a new architecture,
100Base-TX Ethernet, and HS488, the GPIB-ENET/100 delivers
performance comparable to that of plug-in boards.
The GPIB-ENET/100 automatically detects ifthe available network is
10Base-T (10 Mbits/s) or 100Base-TX (100 Mbits/s) and transmits at
the highest availablespeed.
